Matej’s so deep into Flutter under the hood, he probably dreams in Dart — and when he wakes up, he’s still debugging the same list view that gave him a headache last week. Someone get this coder a break before he tries optimizing his coffee brewing algorithm next.

Successfully re-engineered Flutter’s super_sliver_list rewrite, earning solid community praise and contributing a live example for developers to improve their user interfaces with enhanced performance.

To redefine and expand the capabilities of cross-platform desktop development by innovating on existing frameworks and sharing knowledge to empower developers worldwide.

Matej believes that software development should be a blend of creativity and technical mastery, valuing open collaboration and continuous improvement. He appreciates community feedback as a crucial part of creating better, more scalable tools.

His biggest strengths lie in deep technical expertise, creativity in problem-solving, and commitment to open-source projects that foster community growth and innovation.

Matej’s intense focus on complex technical details might sometimes make his communication overly niche, potentially limiting broader audience engagement beyond expert developers.

To grow his audience on X, Matej should pair his technical insights with more relatable storytelling or simplified explanations, making his innovations accessible and exciting to a wider developer and tech enthusiast crowd.

Fun fact: Matej isn’t just content with millions of items in a list—he is proud of making a Flutter list view handle a billion items, proving that ‘more is more’ when it comes to pushing software limits.

A #flutter user reported a bug of UI flickering when using multiple (well, quite a lot of) platform views on macOS. They were very helpful and provided a testcase, so I could reproduce it. Here it is in all its glory. What on earth is going on? Well...

I don't think any #flutter code has given me as much headache as the rewrite of super_sliver_list. Worth it though 🙂. If you're using ListView or SliverList and are not too happy with it, check the live example at superlistapp.github.io/super_sliver_l….

Yesterday we open-sourced bit.ly/super_clipboard and bit.ly/super_drag_and…. It's an early preview, be gentle with it :) Anyone wants to ask me about it in person I'll be at #fluttervikings.

Fun fact, with 129bits of overhead per item a billion item list requires ~16GB of memory. Less fun fact, I tried similar things with #SwiftUI and at 10 000 items LazyVStack became glitchy mess. With no source code or even symbols (!) in the framework pretty much a brick wall.

Well, here we go again github.com/flutter/flutte… Bit frustrating though that instead of looking for solution I'm struggling to even convince people that there is a problem. Does no googler in the #Flutter team have a Windows display with 150% scaling?

Trying to present #kotlin as a general purpose language without so much as having an official LSP seems a bit disingenuous. Weird to see google going all in on a language for which one of the main purposes clearly seems to be driving IDE sales.

One thing constantly missing from #flutter and #SwiftUI comparisons is that with #flutter doesn't hide anything from you. You can see how the sausage is made. Case in point: Arguably SliverList is not very good. But I was able to look at the implementation details, inspect the
